Protecting Muscle Mass While Losing Weight

The Two Pillars of Muscle Protection

Preserving muscle while you lose weight comes down to two things working together: eating enough protein, and giving your muscles a reason to stay through resistance training. Neither one alone does the whole job.

On the Nutrition Side

• Include a protein source at every meal, even small ones.
• Avoid very low calorie intake beyond what your care team recommends.
• Don't go long stretches without eating — see our Nutrition handouts for more detail.

On the Movement Side

• Aim for at least two strength sessions a week (see “A Beginner Strength Routine”).
• Stay consistent even on lower-energy weeks — a shorter session still counts.
• Give your muscles a reason to stick around by challenging them regularly, even gently.

Key takeaway: Muscle responds to being used. Combined with enough protein, regular resistance training tells your body to hold onto muscle even as you lose fat.

Tracking More Than the Scale

Weight alone can't tell you whether you're losing fat or muscle. If you'd like a clearer picture, ask your care team about a body composition scan, like a DEXA or InBody scan. These scans break down exactly how much of your weight is fat versus muscle, giving you a much more complete view of your progress than the scale alone.

Warning Signs to Watch For

• Feeling noticeably weaker with everyday tasks.
• Rapid weight loss paired with low energy or fatigue.
• Clothes fitting looser in areas like your upper arms or shoulders, not just your waist.
• If you notice any of these, message your care team — we can help you adjust your nutrition, activity, or dosing plan.
• starting a new exercise routine, and message us with any questions.
